Researchers at the computer giant have been quietly working on a prototype for a "smart bra" capable of reading your mood, recording activity data, and measuring your heart rate, among many other things. The bra incorporates a small EKG sensor, as well as an accelerometer, a gyroscope, and electro-dermal activities sensors, which feed into a motherboard in the front of the bra. Data collected by the sensors then syncs automatically to a smartphone app (because of course), giving the wearer up-to-date information on some pretty complex body physiology.
In fact, the project was designed to see whether providing information on stress levels in real time would have any effect on eating habits. In other words, if you knew you were stressed, would you be less likely to make food choices based on stress? Sounds promising, but there is one little caveat: The batteries have to be recharged every three to four hours. Ahh, the future. (BBC)
